Worked on improving the accuracy of dnsdist documentation within the PowerDNS/pdns repository by correcting the example for the addMaintenanceCallback function. The update clarified that the callback takes no arguments, ensuring the documentation aligns with actual Lua usage and reducing the risk of misconfiguration for users. Focused on documentation and Lua scripting, the work addressed a specific bug rather than introducing new features, emphasizing careful attention to detail and traceability through a targeted commit. By refining technical documentation, the contribution helped streamline support processes and enhanced the reliability of dnsdist configuration for both developers and system administrators relying on Lua.
